Customer Comments:

"The active splitters work extremely well, and they do not take up a lot of valuable rack space."

Robert Hefele
ANTEK SYSTEMS

Based on Quintech's proprietary L-Band switching technology, the SRF 1750/ABT provides a conventional solution for switching between vertical and horizontal polarities. The SRF 1750/ABT is a terminating A/B switch that operates in the 10-1750 MHz frequency range. Signal flow is controlled by a single contact closure. Power and control functions are applied via feed-thru studs. Its compact aluminum enclosure allows for mounting ease and flexibility. Multiple units can be conveniently integrated into a single rack mount enclosure, thereby maximizing limited rack space.

Note: The SRF 1750/ABT is a bidirectional switch. The connectors labeled "INPUT" may be used as outputs and the connector labeled "OUTPUT" may be used as an input.
